A.)
 
The first thing we must do for this case is to find the area of ​​the complete figure.
 We have then:
 Triangle 1:
 A1 = (1/2) * (1.5) * (1)
 A1 = 0.75 feet ^ 2
 Triangle 2:
 A2 = (1/2) * (1.5) * (2)
 A2 = 1.5 feet ^ 2
 Triangle 3:
 A3 = (1/2) * (0.75) * (1)
 A3 = 0.375 feet ^ 2
 Rectangle:
 A4 = (5) * (0.75)
 A4 = 3.75 feet ^ 2
 Adding the areas we have:
 A = A1 + A2 + A3 + A4
 A = 0.75 + 1.5 + 0.375 + 3.75
 A = 6.375 feet ^ 2
 Answer:
 there are 6,375 feet ^ 2 of plywood in the scenery

 B.)
 
Triangles:
 A = A1 + A2 + A3
 A = 0.75 + 1.5 + 0.375
 A = 2,625 feet ^ 2
 Two layers of paint:
 A = 5.25 feet ^ 2 <45 feet ^ 2
 Rectangle:
 A = 3.75 feet ^ 2
 Two layers of paint:
 A = 7.5 feet ^ 2 <45 feet ^ 2
 Answer:
 
One quart of each color is needed.
